ANTIGLARE ATTAGHMENT,

Application filed August 28, 1925. Serial No. 53,177.

T 0 all whom it may concern: p

Be it known that I, PATRICK W. PADDEN, a citizen of the United States,residing at Toledo, in the county of Lucas and State of Ohio, haveinvented certain new and useful Improvements. in Antiglare Attachments,of which the following is a specification.

This invention relates to an improved anti-glare attachment for motorvehicle head lamps and has for its primary object the provision of asimple, inexpensive and eflicient appliance adapted to be mounted uponthe bulb portion of an incandescent lamp of the type used in connectionwith vehicle head lights, the appliance belng formed to include features0 construction by which the source of light within the bulb is concealedfrom a front view and shadows produced upon the reflector of the lampassociated with the device so that the head lamps may be approached withsafety and security, so far as oncoming observers are concerned butwithout materially diminishing a general illumination capable of being 7produced by the lamps.

A further object rests in the provision of an attachment of thecharacter indicated which is intended primarily to eliminate thenecessity of dimming vehicle head lights upon the approach of oncomingvehicles 1n order to ehminate what is considered to be ative positionupon the bulb of a vehicle head lamp,

Figure 2 1s a front elevation thereof, Figure 31s a verticallongitudinal sectional view, and

Figure t is a front elevation disclosing a variation in the relativepositions of the shadow producing ribs from the positions bulb 3. Thebulb 3 includes the usual filament or light source 4 which is adapted tobe, positioned in approximately the focal center of the reflector.

Adapted to be mounted upon the bulb 3 is the anti-glare attachment 5 comrising In this instance the rivet 9 is of hollow form v to receive thetip 10 of the bulb 3, although it is obvious that in bulbs wherein thet1 is eliminated, the rivet 9 may be of solid form.

integrally formed with each of the body portions 8 of said shields is apair of pliant, flexible fingers 11. These fingers are shapedapproximatel to conform to the spherical form of the ulb 3 and extend toositions adjacent to the base 12 of said bulb or, in other words,between 'said base and the plane of largest diameter of said bulb. Eachof the fingers 11 terminates in a hook shaped extremlty 13 which isadapted to receive a transversely disposed returning spring 14. Thespring 1 is preferably of coil form and serves to exercise a pressure uon the fingers 11 so as to frictionally hold t e latter in secured andadjusted positions of application upon the bulb. It is important incarrying out the invention that the fingers l1 retain definitepredetermined operating positions in connection with the bulb, and forthis reason the spring 14 is employed so that the fingers will exercisesufiicient pressure on the bulb to retain the attachment in its adjustedpositions of application. This is preferable over a construction whereinthe fingers themselves are utilized to clamp the attachment in placesince it has been found in this latter form of construction that theattachment tends torotate on the bulb and cast shadows which do notmaterially alleviate lamp glare. In use, my improved attachment isapplied and the ribs or fingers 11 are set in. relation to the source oflight so that the light rays which produce the glare streaks observableon an ordinary reflector, are intercepted by the opaque fingers or ribs.It will be noted that by the employment of a plurality of shields, whichare relatively adjustable, the fingers or ribs may, by relativeadjustment, be set at positions securing the most effective eliminationof the glare. By the employment of the spring 14 it is simply necessaryto employ but four of the ribs 11, since the latter do not serve asholding members but merely as glare arresters.

The invention thus provides a simple and readily adaptable attachment bymeans of which lamp glare is greatly minimized and yet an ellectivedriving light produced. lt will be observed that the small number ofribs employed leaves wide spaces between said ribs by means of which thelight from the bulb may pass through the reflector in an unobstructedfashion. My device has the advantage of being capable of instantapplication to an ordinary light bulb and enables the driver of amachine so equipped to operate the vehicle without dimming the headlights upon the approach of oncoming vehicles.

ll til l tltllil What is claimed is:

1. An anti-glare attachment for motor vehicle head lamps comprising apair of shields, each of said shields being formed to include a bodyportion and a plurality of lamp bulb embracing ribs, and a pivotalconnection be tween the body portions of said shields permitting ofrelative adjustment: of said ribs about the longitudinal axis of thelamp bulb upon which the shields are applied.

2. An anti-glare attachment for motor vohicle head lights, comprising apair of opaque shields, said shields including aligned body portionspositioned in front of said bulb, an axial pivot uniting said bodyportions for relative rotation, rearwardly extending' ribs formed withsaid body portions and engaging with the outer walls of the lamp bulbupon which the attachment is mounted, said ribs being relatively adjustable by said axial pivot, and a clamping springcoopcrative with the endsof said ribs to maintain the latter in fined positions of adjustment inconnection with said bulb.

ln testimony whereof I aiiix my signature.
